Commissioning
8.3 Commissioning using the BOP20 operator panel
SINAMICS DCM DC Converter
276 Operating Instructions, 12/2018, A5E34763375A
Note
For 2Q devices, the rated DC voltage of the SINAMICS DCM specified in the technical data,
can only be achieved if the
α
G
limit (p50150) is set to 5°. The factory setting is 30°. In order
to reach the rated motor voltage (p50101[D]), the
α
G
limit must also be changed to 5°.
〈5〉Data for actual speed value acquisition
〈5.1〉Operation with analog tachometer
p50083[D] = 1
The actual speed value comes from the
"Main actual value" (r52013)
channel (terminals XT1-103, XT1-104)
p50741[D]
Tachometer voltage at maximum speed (
– 270.00 to +270.00 V)
Remark:
The value set here determines the 100% speed for the closed
-loop speed
control.
p2000
Speed in rpm for tachometer voltage set on p50741[0]
Comment 1:
Parameter p2000 is used to convert from a
"physical speed" (rpm) into a
"
relative speed" (%) and vice versa.
This conversion is required for:
•
Speed setpoint input via the control panel in STARTER
•
Speed setpoint input via the operating screen form at the AOP30
•
Calculation of display values r0020, r0021, r0060 and r0063
Remark 2:
Parameter p2000 and parameters r0020, r0021, r0060 and r0063 are not
data
-set dependent. This is the reason why the physical speed can only be
displayed correctly for one data set (DDS).
〈5.2〉Operation with incremental encoder
p50083[D] = 2
The actual speed value comes from an incremental encoder (r0061)
connected to terminal block X177.
p0400[0]
Encoder type selection
p2000
Speed in rpm at 100% speed
Remark:
The value set here determines the 100% speed for the closed
-loop speed
control.
